Background

Ever since the Chinese Kongsi came to Central Kalimantan in search of gold and diamonds in 100 AD, the region’s alluvium-rich river beds have been a magnet for miners, ranging from Indian trading companies to the famed Dutch East India Company.
More recently, miners have been exploring Kalimantan for zircon as steady growth in scientific advances and industrial applications have made Kalimantan’s premium zircon an essential mineral across a wide range of applications.
Today, as producers export large quantity of mineral sands, Kalimantan still boasts vast reserves of proven but yet untapped deposits of minerals, including rutile and ilmenite among others.

A region rich in mineral sands

Mandiri – a licensed concession covering an area of 2,032 hectares in Central Kalimantan – is devoted to the exploration of mineral sands products and the production and export of premium 65.5 grade zircon.

With zircon inferred resources of 6.0 Mt, Mandiri represents the largest global zircon discovery since 2012 and the world’s 5th largest producing mineral sands deposit. Including zircon, Mandiri’s heavy minerals inferred resources exceed 9.4 Mt, with substantial additional exploration potential across the Mandiri tenement.

Featuring zircon assemblage of 64% and a very long mine life, Mandiri also benefits from much lower normalised mining costs than competitors due to the high assemblage value and low required capex associated with Indonesia’s zircon deposits.

Already in its 4th year of operation, Mandiri has produced, processed and sold in excess of 11,000 t of premium zircon and is set to significantly scale up production to meet the fast-growing global demand for premium zircon. We expect to reach a production capacity of 48kt of premium zircon per annum within 5 years.
Today, as producers export large quantity of mineral sands, Kalimantan still boasts vast reserves of proven but yet untapped deposits of minerals, including zircon, rutile, ilmenite among others.
